System Navigator | Software and Firmware |Resources

QSC SysNav^™ is an application intended to be used with L Class compatible products. It allows the user to easily design, configure, control, monitor and apply signal processing to individual L Class loudspeakers or full arrays.

The SysNav App also allows you to directly update all L Class loudspeakers’ firmware using a network connection to the L Class loudspeakers and a Wi-Fi router. For detailed information, please consult the online SysNav Help.

While the preferred method for updating your L Class products is to use the SysNav App, there are certain cases where the L Class Firmware Updater App (Windows only) should be used.

Release Notes

QSC SysNav^™ (System Navigator)

Version 1.2.0048
QSC SysNav™ (System Navigator) software version 1.2 offers a number of additional functionalities as well as bug fixes.

Compatible Loudspeakers
LA108 active line array loudspeaker 8-inch 2-way - firmware version 1.1.0068
LA112 active line array loudspeaker 12-inch 2-way - firmware version 1.1.0068

Firmware Update Caution
Please be aware that the L Class loudspeaker settings will be reset back to factory default during the firmware update process to version 1.1.0068.
Prior to installing SysNav version 1.2.0048 and performing loudspeaker firmware updates (1.1.0068), it is highly recommended to create a backup of all crucial settings that have been previously applied to the array and/or loudspeakers. To learn more about such procedure, please consult the following article - Firmware update impact to user data - in our Knowledge Base.

New Features

AIM Auto Splay available for flown array deployments
AIM SPL graph enlargement
Network settings editing functionalities
Display of array top angle tilt
Display of Dante MAC settings
Added notification on multicast failure
Factory Reset and Diagnostic Test controls available

Bug Fixes

Shading on/off now affects audio when off
Ar-Q changes are reflected in SysNav also
LED/LCD Controls update in SysNav also
Improved scrolling on Windows computers
Standing/Seated preferences are reflected in AIM
Improvements to AIM displays and controls

Known Issues

In Demonstration Mode there are several features / controls that are not working properly.
- Array optimization and modified parameters in the array do not propagate to individual loudspeakers.
- Changing some controls has no effect.
The array name cannot be edited.
Network disruptions during firmware updates could cause a unit to not update properly.
- Refer to Loudspeaker Firmware Update Best Practices for instructions on how to ensure a successful update.
AIM Auto Splay
- Auto Splay is currently not available for deployments other than Flying. A future version will support Auto Splay for all deployments.
- As the height of a surface that is fully behind the array increases (this is often the “Stage” area), Auto Splay will erroneously take that height into account and recommend an angle that tilts the array upward more than it should. A future version will address the issue.
- Workaround: For the purpose of an accurate Auto Splay calculation, either remove the area from the venue, or change its height to zero.
Changing too quickly controls that are passed through an array via IR (infra-red communication) can cause the array to become un-optimized including parameters like Gain, Delay, Sensitivity, HPF, and controls relating to Array Shading such as Compare.
- Workaround: Wait a couple of seconds between changes to allow time for the firmware to send the commands to every loudspeaker in the array.
Dante subscription status can sometimes continue to stay red as if there was a lost connection even though the connection has been revived.
- Workaround: Restart SysNav
In Utility menu, changing re-calibration to "User Calibration" causes the loudspeaker array to go into "Un-optimized Array Configuration".
- Workaround: Change the recalibration setting to “Factory Calibrated” for the error message to disappear.

Previous Versions

Version 1.1.0026
This is the initial public release of QSC SysNav™ (System Navigator), an application that is used to design, configure, control, monitor and apply signal processing to compatible QSC L Class loudspeakers and full arrays.

Compatible Loudspeakers
LA108 active line array loudspeaker 8-inch 2-way - firmware version 1.01.0033
LA112 active line array loudspeaker 12-inch 2-way - firmware version 1.01.0033

Known Issues

The Telemetry screen displays fields for Presets. The Preset function is not yet operational.
If the SysNav host device enters sleep mode, the SysNav App may be unresponsive upon waking.
- Work-around - when running SysNav, set the host device to stay awake.
The array name cannot be edited directly.
- Work-around - To rename the array, change the name of the uppermost loudspeaker in the array, power cycle the loudspeakers and restart SysNav.
Sending extremely rapid changes from SysNav may result in connected L Class loudspeakers losing synchronization with the SysNav App, which will then display erroneous system information. Closing and restarting SysNav will restore synchronization.
Telemetry messages (Meters, Temperature, and AC Volt) coming from the L Class loudspeakers can be blocked by some routers. Causes and work-arounds…
- Another application on the SysNav host device / computer may be using the same port as SysNav to get telemetry from the loudspeakers. If using a desktop computer connected via Wi-Fi, disconnect Wi-Fi and use a wired connection.
- Shut down all other applications on the SysNav host device.
- Restart the SysNav host device.
- Configure the router so that IGMP Snooping is not enabled.
- While most routers or switches should work with a SysNav network, a list of routers and switches that have been tested by QSC can be found here: QSC Network Products
Changing the network settings on the loudspeaker from DHCP to Static and vice versa, may not update the information in SysNav.
When LED Mode and LCD Brightness controls are updated from the loudspeaker, SysNav does not show the updated value until restart of the application.
When the Ar-Q settings for a loudspeaker are changed from SysNav, the values on the loudspeaker are updated but will not be reflected in SysNav until restart of the application.
Changing the Standing and Seated Audience Ear height in the General Preferences page does not affect the values in AIM. AIM shows 5 feet (1.5 m) for Standing, and 3.5 feet (1.1 m) for Seated. Also, when changing from Imperial to Metric and back, the values are not correctly converted.
Firmware update info from the QSC server can take a few minutes during which the Home Page status and/or the Updates page may show incorrect information. Go to the Updates page, allow 4-5 minutes, then click the Check for Updates button.
The loudspeaker firmware currently does not fully support the HF Shading In/Out feature shown on the Array Page. The user can change the Gain values.
Some control labels may not resize properly with some screen or device sizes and some labels may be truncated.
In Demonstration Mode there are several features / controls that are not working properly.
- Array optimization and modified parameters in the array do not propagate to individual loudspeakers.
- Changing some controls has no effect.
In AIM
- Windows only - A flying array can be dragged beyond the intended tilt angle limit of +/-45 degrees after which the array cannot be dragged again. Normal operation may be restored by entering a value between -45 and +45 degrees using the keypad.
- Windows only - For some screen sizes the SPL Frequency control is cut off. This does not affect the use of the control.
- When entering a filename during a New or Save As operation, entering a duplicate file name will cause a "duplicate file" warning dialog to open behind the main dialog, rendering the UI inoperable. The work around is to restart the application. Doing so will not cause any loss of data. The AIM venue and array should be in the same state as prior to the issue and may be saved with a non-duplicative name.
- Some fields will allow larger values to be entered than within reason. This may have undefined effects on the UI, model graphics and/or SPL calculations.
- When using Ground Stack/Tripod deployment, the Y-Position can manually be set to a value higher than the height of the floor or area it's on, even though the UI does not display the change.
